Bulk domain authority check

Domain scoring from free/public sources: Domain Rating (Ahrefs), Open PageRank, Tranco rank and CrUX presence with Core Web Vitals. All keys stay on the server — they never reach the browser.

Domains (one per line, up to 500)

Empty lines and duplicates are dropped. Sorted by DR (highest first).

What the columns mean and where the data comes from

DR (Domain Rating) — backlink profile strength on a 0–100 scale (Ahrefs, free domain-rating-free endpoint). Open PageRank — an independent authority score of 0–10 based on the Common Crawl link graph (Open PageRank; the CSV also includes the number of referring domains). Tranco — a domain's global popularity rank (lower = more popular; tranco-list.eu). CrUX — whether the domain has real Chrome UX Report field data and whether it passes Core Web Vitals (LCP/INP/CLS, mobile p75).

Data is fetched by a server-side proxy (Ahrefs/CrUX/OpenPageRank keys live in .env, not in the browser). If a source is unavailable for a domain, the cell shows "—". DR license: ahrefs.com/legal/domain-rating-license.
